BZ: 44910

Creates two commands that can be called through the command
line of the parameter-framework. First command getDomainXML
returns a string containing the xml structure of the
domains, configurations and settings. Second command
getSystemClassXML returns a string containing the xml
structure of all the instantiated parameter with their
attributes.
